Surface modification of polysulfone (PSf) surface, via acrylic acid (AA) surface graft polymerization, induced by atmospheric pressure Air plasma (Air APP) treatment, was explored for imparting UF membrane fouling resistance and tuning its performance. PSf activation with APP subsequent tethering PAA chains resulted in a higher degree hydrophilicity relative to the use He He/O2 plasmas. Surface-nano-structed (SNS) membranes tethered were increased polar component energy 14% 556%,...
Scale up of atmospheric pressure plasma-induced graft polymerization (APPIGP) was demonstrated for surface nano-structuring (SNS) a base polyamide (PA) reverse osmosis (RO) membrane with tethered poly(acrylic acid) (PAA) chains. Large SNS-PAA-PA sheets, measuring 76.2 cm × 60.9 cm, were synthesized and used to fabricate small spiral-wound low fouling seawater RO elements (2.5 in. 21 in.). The sheets high spatial uniformity respect both water permeability salt rejection. Lower propensity,...
The gypsum and calcite scaling propensities of the thin-film composite polyamide (PA-TFC) reverse osmosis (RO) membrane, modified with a tethered surface layer polyacrylic acid (PAA) chains, was evaluated compared to selected commercial RO membranes. PAA synthesized onto membrane (i.e., base-PA) via atmospheric pressure plasma-induced graft polymerization (APPIGP). nano-structured (SNS) base-PA (SNS-PAA-PA) scaled lesser degree, as quantified by lower permeate flux decline imaging, relative...
A membrane-based emulsion separator can enable continuous solvent extraction in bioprocessing separations with substantially improved demulsification and mass transfer rates, including where formation is a challenge.
Stimuli-responsive polysulfone (PSf) ultrafiltration (UF) membrane was developed via surface modification with tethered hydrophilic polyacrylic acid (PAA) chains of length greater than the native pore size. The nano-structured (SNS) synthesized atmospheric pressure plasma-induced graft polymerization (APPIGP) to form a PAA brush layer. SNS-PAA-PSf UF demonstrated hydraulic permeability and selectivity in ranges 0.74–2.29 × 1013 m−1 1.8–15.0 kDa, respectively, response changes pH (3–11) ionic...
Abstract Peroxisome proliferator-activated receptor γ (PPARγ) is a master transcriptional regulator of systemic insulin sensitivity and energy balance. The anti-diabetic drug thiazolidinediones (TZDs) are potent synthetic PPARγ ligands with undesirable side effects, including obesity, fluid retention, osteoporosis. 15-keto prostaglandin E2 (15-keto-PGE2) an endogenous ligand metabolized by reductase 2 (PTGR2). Here, we confirmed that 15-keto-PGE2 binds to activates via covalent binding. In...
During the production of many bio-based chemicals from fermentation and enzymatic processes, product separations frequently represent most expensive energy-intensive unit operations in an integrated process, often due to low concentrations target bioproducts. In this study, we high-pressure reverse osmosis (HPRO) concentrate exemplary product, butyric acid, prior downstream extraction. Through both modeling experimental measurements, identified major factors limiting maximum achievable...
The COVID‐19 pandemic has underscored the paramount importance of maintaining clean and safe environments. Strengthening environmental purification measures is pivotal for better preparedness resilience against future health crises. Photocatalytic fibers, due to their versatility adaptability various application scenarios, play a role in field purification. In this perspective, light shed on advancements employing photocatalytic fibers tackle issues encompassing dye degradation, antibiotics...
Shallow estuarine habitats are normally characterized by wide interannual and intraannual fluctuations in water-quality variables, including dissolved oxygen; however, the short-term variability variables is seldom measured characterized. Water-quality data collected semicontinuously automated sondes from 1995 to 2000 at 55 sites among 22 National Estuarine Research Reserves (NERR) were analyzed characterize temporal compare conditions systems regions. Three-way analysis of variance (ANOVA)...
